The National Environmental Policy Act (NEPA) mandates federal agencies to assess the environmental impacts of proposed major actions. During the period from 2017 to 2021, the executive branch implemented several revisions to the regulations governing this process. These modifications altered the scope and depth of analysis required for infrastructure projects, resource management decisions, and other federal undertakings. For example, specific changes concerned the definition of “major federal action” and the extent to which indirect and cumulative effects needed to be considered.
These regulatory adjustments aimed to streamline project approvals and reduce perceived bureaucratic obstacles. Proponents argued that the changes would accelerate economic development and infrastructure modernization by shortening the time required for environmental assessments. Detractors, however, expressed concern that the revised rules could weaken environmental safeguards and limit public input in decision-making processes, potentially leading to adverse ecological consequences and diminished transparency.
